We had developed a very unique motor technology adopting low cost ferrous magnet instead of very expensive REM but showing very high efficiency/energy savings/energy density, variable speed/torque and low manufacturing cost. Our motor will be very useful for energy savings and low cost in such industries that require high efficiency, variable speed/load, high starting torque and minimal heat generation. We are in preparation to perform a full cycle field test on 50 HP air compressor system.
